Specific implementation mode
The embodiment of the utility model is described in further detail below in conjunction with the accompanying drawings.
Embodiment one, referring to figs. 1 to Fig. 2, filter press provided by the utility model includes pairs of mating pressure plate 7 and stops
Push plate 9 is provided with 2~120 filter plates 8 between pressure plate 7 and thrust plate 9, is additionally provided with for pushing pressure plate 7,8 and of filter plate
The large-diameter F.F. that thrust plate 9 closes up goes out device soon.
It includes hydraulic cylinder 1, the piston rod 13 and compression of hydraulic cylinder 1 that large-diameter F.F. provided by the utility model goes out device soon
Plate 7 connects.The large-diameter F.F. goes out device and further includes air compressor 6, provides liquid for the rodless cavity 11 to hydraulic cylinder 1 soon
The diaphragm type gas-liquid tank 3 of pressure oil, the diaphragm type gas-liquid tank 3 include air bag 310, oil inlet and outlet 33, air inlet/outlet 34, the gas
Capsule 310 is set in the tank body 30 of gas-liquid tank 3, and the cavity in air bag 310 is fluid chamber 31,310 lateral wall of air bag and tank body 31
Gas chamber 32 is formed between madial wall, the fluid chamber 31 is connect by oil inlet and outlet 33 with the rodless cavity 11 of hydraulic cylinder, described
Gas chamber 32 is connect by air inlet/outlet 34 with air compressor 6, and the rod chamber 12 of hydraulic cylinder 1 is connect with air compressor 6.
Gas chamber 32, the hydraulic cylinder that the output end of air compressor passes through 3 position-5 way center-leakage type solenoid valve and diaphragm gas-liquid tank
1 rod chamber 12 connects.3 position-5 way center-leakage type solenoid valve is widely used at present, structure and principle and prior art phase
Together, it is only briefly described here.3 position-5 way solenoid valve sets there are one the air inlet being connect with air compressor, controls two rows
